front window regulator- repair
replace window regulator-drivers side [front]
The 1999 Chevrolet Malibu is part of the fifth generation (1997-2003) manufactured by General Motors. This is the first smaller, front-wheel-drive Malibu that General Motors put back on the market after the Malibu line was temporarily discontinued in the early 1980's.
I hate these when they brake. Sometimes there are specialty tools involved, but all of the Haynes manuals I have show how to remove the regulator. The biggest problem is that it's not usually the regulator that is bad, it's usually the motor. I'm assuming that is the case with your car. Be careful, as there is a strong spiral spring that counterbalances the weight of the window. The problem with this repair is typically not the assembly, it is usually the putting it all back together. Have a roll of duct tape and a person to help you. The duct tape can be used to hold the window still in various positions on the track by using lengths of it wrapped over the top of the window frame and stuck to both the inside and outside surfaces of the glass. You can vary the position of the window, and thusly the position of the regulator rails as you assemble. Again, be careful with that spiral spring, and take notes or pictures of the way that spring is installed. Let me know if you need more help.
